Would that we'd have had Patriarchs like Catholicos Mkrtich Khrimyan of blessed memory at that time.
The were also a number of revolts in upper Egypt as well; brave men who fought off their Arab overlords with nothing but farming tools. But without the whole nation rising up, these efforts were all doomed from the start.
Here's the entry on the revolt from the Coptic Encyclopedia:
"Thus ended the last revolt of the Copts in Egypt. Without any
real political plan or any national leadership, without any organized
armed force, and in the face of a strong, experienced army, these
spasmodic revolts were an indication of desperate courage. Not only
did they achieve nothing but they drained the force and pride of the
Copts. Nonetheless, these revolts are important for Coptic history, as
they shed light on the character of the Coptic masses."http://ccdl.libraries.claremont.edu/cdm/singleitem/collection/cce/id/326/rec/8
